Longines is one of the oldest Swiss watch manufacturers with an unparalleled history of invention, innovation, patents and awards. The company is also responsible for some of the most beautiful watches ever made, but has been something of a Cinderella among the watch collecting fraternity until recently. Longines is now rightfully returning towards the elevated status it once held in the pre and post-war years when it ranked among the very best among of the Swiss watch manufacturers. It is really only within the past three years that Longines vintage watches have risen again to receive the admiration and popularity they deserve, with values rising of by around 15 – 20% per year, and on certain models, such as the now legendary Longines Calibre.13ZN chronograph, prices have sky-rocketed.


Here we have a wonderful example of typical Longines elegance and style in the form of a beautiful 9ct gentleman’s dress watch from 1951. This was a period when technically, Longines was approaching its peak and competing head to head with all of the top-tier Swiss watch manufacturers. Notable highlights on this watch are its beautiful previously restored dial with original hands and the subsidiary seconds dial at 6 o’clock. The case and high grade Calibre 12.68Z movement are also in stunning condition.

The Dial

The dial is simply wonderful due to its age and excellent previously restored condition. It is typically 1950s in its use of a subsidiary seconds dial and thin ‘lance’ style hands, matched with a mix of ‘spearhead’ hour indices and standard arabic numerals at 3 – 6 – 9 – 12, all perfectly placed over a slightly cream dial. Longines always seems to aim and achieve dials which are that bit closer to perfection and does this so often and so effortlessly.

Even the Longines signature looks more ‘in place’, which incidentally is the oldest registered, of any watch manufacturer. The company certainly made a fine art of this during the ’50s and ’60s. Perhaps the evolution of a certain style became part of the company’s DNA, but Longines dials seem in a class of their own. This sense of style has certainly won Longines many loyal customers, who only later came to appreciate the accuracy and reliability of its movements.

The dial is simply signed ‘Longines’ with ‘Swiss Made’ at the very bottom.

This watch has been previously restored to a very high standard and remains in outstanding condition.

The Movement

The watch carries its original Longines Calibre 12.68Z, hand-wound movement which carries all the purity and charm typical of a top-class 1950s Swiss watch movement. This is one of the classic manually wound movements of its day, with 17 jewels, a running rate of 18,000 half beats per hour and a power reserve of 41 hours. It has every contemporary refinement, including a bi-metallic balance and an Incabloc shock protection, which was still a relatively recent introduction in early 1950.

If a dial defines the look of a vintage wristwatch, then it is the hand-built movements inside that are at its heart and makes them of such interest in the first instance. These minor miracles of micro-engineering were built long before the advent of CNC machines and computer-controlled polishing lines. While some machinery was obviously used in movement manufacture, it was of a very traditional nature supervised by specific individual craftsmen, exactly as had been the case since the 19th century. Each component was individually inspected and finished until it met with the watchmaker’s satisfaction and then gradually built up into a complete movement and regulated again by hand. If one really takes time to understand this process and the quality present in these classic watch movements by makers such as Longines, it really is breathtaking. This, of course, accounts for their high prices when new and the prices which good vintage examples command today.

Returning to the quality of finishing and build, this is exceptional and fair to say this is a better-finished movement than any equivalent watch offered by Rolex or Omega at the time. Unlike its two famous competitors, which simply fitted jewels into drilled holes in the bridges, Longines adopted the system of screwed chatons, by which every jewel is held in its own threaded brass sleeve, which is then in turn screwed into the plates. This is a lovely refinement that one hardly ever sees below the top tier and must have added significantly to the cost of production when new. The fact that vintage Longines watches are still so affordable today is hugely fortunate when we actually look at them closely and see how beautifully well made they are.

As can be seen, the movement is in absolutely tip-top condition following a thorough overhaul and service by our vintage Longines specialist watchmaker. This means the movement has been completely disassembled, cleaned, inspected and rebuilt using only original Longines parts where required, then carefully calibrated and tested. Upon return, this watch is now running to within +6 seconds per day which is absolutely outstanding for any vintage watch of this age. When fully wound, this movement also has a 41-hour power reserve.

These movements are very accurate and reliable, making it completely practical and appropriate for regular everyday use. Our watchmaker has indicated this particular movement is in top condition and with regular servicing every 2 to 3 years, we would fully expect this watch to run very happily for many more decades to come! We are therefore very pleased to offer a 12-month warranty on this watch movement* and servicing in the future, as required. ‘Longines’ is signed on the bridge, together with ‘17 Jewels’ and ‘Swiss Made’. Also found here is the calibre number 12.68Z and the serial number 8757126 indicating this watch was produced in 1951. All this detail has been painstakingly filled in with 9-carat gold in order to increase its legibility against the background. These points, though minor in themselves, elevate Longines movements of the time, to something which is a cut above the rest.

*Please note – our 12 months’ warranty is only applicable if the full list price is paid.

The Case

The styling of this model is absolutely classic and timeless. The 9ct yellow gold, large, round, ribbed case with straight lugs in absolutely wonderful, original condition and measures 34mm in diameter, excluding the correct, original unsigned crown.

The inside of the case-back is all marked correctly. At the top is ‘DS & S’ which was the sponsor’s mark of David Shackman & Sons. Based in Chesham, Buckinghamshire, Shackman was an independent case-making concern that supplied its products to most of the major Swiss houses for use on their watches that were to be sold in the UK.

Experienced collectors will also know Shackman cases well on Omega, Jaeger Le Coultre and more commonly, Rolex models from this era, which are very highly universally regarded for their high quality. Gold Swiss watches sold in Europe tended to have Swiss made cases, but those supplied to the British market were invariably UK made. This came about after the ban on the import of precious metal into the UK imposed by the British government in December 1916. Needing to service their most lucrative market, the Swiss houses skirted the obstacle by shipping only uncased movements to their UK agents and having these housed in British made cases upon arrival, these of course not being subject to any restriction. Long after the ban was lifted, this same arrangement continued, basically because it was so convenient for all involved. Ironically, given that they were first used as a temporary stopgap in a crisis, the quality of British made cases proved to be so high that they now typically command a slight price premium over their Swiss equivalents.

‘Baume’ is stamped exactly as it should be. Baume & Co, of 1 Hatton Garden, London, EC1, acted as official British agents for Longines since the World War I period. On an earlier watch, we would expect to find the initials “AB” inside the case-back, these being those of Arthur Baume, the company’s Managing Director. However, by the 1950s, the full Baume signature as seen here, was used instead.

On a watch clearly sold when new in the UK, we would expect to see a full set of British hallmarks. These are indeed here and inform us that this case was assayed as 9ct gold in London, 1951. The case-back also carries the case reference number 640.

As always, our standard advice applies: Vintage Watches should be kept clean and dry at all times.

In Conclusion

The watch here is a superb example of a most beautiful and sought after vintage Longines. A rare, usable and highly collectable vintage gold gentleman’s dress watch, from one of horology’s most highly respected names which is a thing of beauty, to use, to wear, to treasure and to enjoy!

This watch will also make an excellent investment and family heirloom piece. Even though vintage Longines prices are still catching up with, for example, Omega, JLC and Rolex, we are sure fine examples such as this still remain undervalued. As each year goes by and the world market for vintage gold watches continues to expand, availability will become more limited, meaning prices are surely destined to climb ever higher!

We have always been great admirers of vintage Longines and for many years they have been significantly undervalued. However, this has begun to correct itself in recent years. There is no good reason for this, as these watches technically match or surpass almost all the high-end brands. Whatever the reason, they still represent excellent value even though prices have been increasing by around 20% per annum during the past few years.

A word on our prices – We always try our hardest to acquire the very highest quality watches we can find, before restoring them to the highest possible standards. We then offer these at the fairest prices we can, taking into account our pre and post-sales care and service. This approach means we will never be the cheapest, but nor will we be the most expensive. Indeed there are some well-known stores in West London which are highly successful charging between two to three times the price you see here. We, therefore, consider our prices to be fair, given the quality of watches we have to offer.

Please note, we also welcome part exchanges. If you have a watch or a small collection for sale, please contact us as we will be happy to discuss this.

We will also be happy to Service your watch, Repair your watch or Restore your watch, all at ‘sensible’ prices. Please see here.
